It only took a few minutes to replace my existing OEM harness on my 920XT which was starting to break. The order came with 2 screwdrivers, a pen and screw for each strap and of course 2 halves of the group. Simple instructions with a photo (no words) were also included. You will need both screwdrivers as the pin will rotate if you try to unscrew just one side. The first swap went fine, but the second side had an issue as the head of the screw broke off when I was tightening it. Maybe it was my fault that I overstretched it. I just reused one of the old pens and finished the job just fine.
